1. Jon Elster, France Before 1789: The Unraveling of an Absolutist Regime. A useful historical introduction to the period, but most notable for taking canons of good social science explanation seriously throughout each step of the analysis. For one thing, it helps you realize how few people do that, but at the same time you wonder how much restating events in terms of social science mechanisms actually helps historical explanation. A smart book and very well-informed book in any case.
2. Paul Preston, A People Betrayed: A History of Corruption, Political Incompetence and Social Division in Modern Spain. A highly detailed but also analytical account of how Spanish political economy became so screwed up. Runs from the 1830s up through the financial crisis, and focuses why Spain was backward in nation-building. Maybe too detailed for some but I believe there is no other book like it.
3. Henry M. Cowles, The Scientific Method: An Evolution of Thinking from Darwin to Dewey. Argue that the true scientific method did not develop until the mid-to late 19th century. A good book, although perhaps more for historians of ideas than students of science per se.
John Anthony McGuckin, The Eastern Orthodox Church: A New History is both a good introduction and deep enough for those well-read in this area.
There is also Paul Matzko, The Radio Right: How a Band of Broadcasters Took on the Federal Government and Built and Modern Conservative Movement. I don’t listen to (non-satellite) radio, but some of you should find this interesting.
